Answer:
The values is
The direction is out of the plane
Explanation:
From the question we are told that
The magnitude of the electric field is
The magnitude of the magnetic field is mathematically represented as
where c is the speed of light with value
Given that the direction off the electromagnetic wave( c ) is northward(y-plane ) and the electric field(E) is eastward(x-plane ) then the magnetic field will be acting in the out of the page (z-plane )
Answer:
The electric force on the top charge is .
Explanation:
Given that,
Electric charges in a thundercloud,
The distance between charges, d = 2.3 km = 2300 m
Let F is the electric force on the top charge. The electric force is given by the formula as :
or
So, the electric force on the top charge is . Hence, this is the required solution.
